Vantaggi
AZ, like all big pharmaceuticals companies, has been rocked by generic competition, government regulations, etc. but still tend to pay very well, provide good if not excellent benefits, comfortable work environments, training opportunities and opportunities for advancement. AZ also works hard to be recognized as, ethical, diverse, flexible, family friendly and an all around good place to work. In my view they did not always achieve this in all areas of this huge organization but the effort was always present.
Svantaggi
AZ, like most big companies, is too bureaucratic. While down-sizing, the work-life balance message rings hollow because those who manage to keep their jobs are working more and more hours. This can't be helped and employees are smart enough to realize it without holding much of a grudge.
